CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of European Patent Application Nos. EP17182881.7, filed Jul. 24, 2017, and EP18183785.7 filed Jul. 16, 2018 the entirety of each of which is hereby incorporated herein by reference.

BACKGROUND OF THE INVENTION 1. Field of the Invention

The present invention relates to a smart beverage vessel or a smart carafe for monitoring the water consumption of a user of the beverage vessel and for ensuring that a beverage of reasonable quality is provided to the user. Further, germ formation can be avoided.

2. Description of the Related Art

Depending on the physical activity of the user a user has to drink a certain amount of water comprising certain types and amounts of minerals.

Generally, water is consumed by humans increasingly from bottles, since tab water is not considered to be tasty or is more or less polluted. These circumstances cause negative effects. A big share of the bottles is plastic bottles. Such plastic bottles emit substances hazardous to health. Further, the environment is polluted by plastic bottles.

In the heat of the summer the plastic bottle may get very hot, even during delivering the bottle to a customer. Thereby, even more substances hazardous to health can be emitted from the plastic to the water. Plastic is a nutrient medium for bacteria multiplying in the heat in the bottle. Accordingly, the quality of water in the bottle is unknown.

Drinking vessels of the prior art do not monitor quality of the beverage stored in the drinking vessel.

Carafes are used when a group of persons wishes to drink the same beverage, such as during breakfast, lunch, dinning or during a meeting.

Carafes of the prior art face the problem that portions of a closure element over which water flows have to be touched by hand. This is not desired under hygienic considerations.

Further, closure elements of carafes of the prior art comprise plastics that may get into contact with the beverage. This is also not desired under hygienic considerations.

Further, the quality of the water in the carafe has to be monitored and the user has to be informed, if the quality of the water in the beverage vessel is too low.

WO 2016/090235 A1 relates to a portable vessel, wherein additives located in containers can be added to water in the vessel. This system has the disadvantage that the quality of the water cannot be monitored and that it is intricate for the user to carry a comparably bulky beverage vessel with a plurality of containers throughout their working days and leisure days.

WO 2016/155538 A1 discloses a vessel that can monitor drinking events.

It is an object of the present invention to provide an improved beverage vessel that solves the problems of the prior art.

SUMMARY OF THE INVENTION

A beverage vessel according to a first aspect of the present invention comprises a beverage container, a closure element, a light distributor element and a light emitter. In the beverage container beverage may be stored. The beverage container has an upper opening through which beverage may be poured in and poured out of the beverage container and a wall extending from the opening at the top to the bottom of the beverage container. The beverage container may be rotational symmetric along the vertical axis of the beverage container. The closure element is adapted to be releasably positioned in the upper opening of the beverage container. The light distribution element is arranged at the closure element. The light emitter is positioned such that the light emitted by the light emitter passes at least a part of the volume of the beverage container before entering the light distribution element. The light distribution element is adapted to distribute the light entering from the light emitter in the periphery of the beverage vessel.

The inventive configuration allows combining design aspects and functional aspects. The light emitter may be positioned at a location close to a controller and an accumulator. The light distribution element may be positioned remote and spaced apart from the light emitter and integrated into the design of the beverage vessel, such as a smart carafe, smart bottle or the like. The light emitter may display at least one information relating to the beverage in the beverage container by an optical signal. The light distribution element distributes the light emitted by the light emitter in the periphery of the beverage vessel. Thereby, the user of the beverage vessel or service staff can recognize that action is required, such as refilling the beverage vessel, replacing the beverage in the beverage vessel.

The light distributor element may have opaque optical properties, scattering optical properties and/or diffracting optical properties for appropriate light distribution around the beverage vessel, such that the light and the information about the beverage may be recognized by the user and service staff in the periphery of the beverage vessel.

In one embodiment, the light distribution element may be positioned atop of the closure element.

The closure element may comprise a light guide, a hollow portion or the like for passing light emitted by the light emitter to the light distribution element after it has passed through the beverage container and/or the beverage in the beverage container.

The light emitter may transmit light in a plurality of different colors. The light emitter may transmit continuous light, flashing light or light periodically changing color, e.g. for transmitting information.

In one embodiment the light emitter is positioned at the bottom of the beverage container. The light may pass through the beverage.

The beverage vessel according to a second aspect may comprise a closure element comprising a locking mechanism. The locking mechanism comprises at least three locking arms extending in radial direction of the beverage container to the beverage container. At least one arm of the locking element comprises an elastic portion being elastic in the radial direction of the beverage container.

In one embodiment, the locking element may only be elastic in the radial direction. However, the locking element may also be elastic in another direction.

The beverage container may comprise at least one concave portion in the wall, wherein the concave portion extends in the radial direction of the beverage container. The concave portion extends in the radial a direction from the inner to the outer of the beverage container. The concave portion forms a recess directed to the middle axis of the beverage container. The arms releasably engage the concave portion in the wall for releasably locking the closure element to the beverage container.

The closure element can be pushed by a user into the beverage container through the upper opening. The locking arms are retracted by the outward tapper of the beverage container next to the opening. In other words, around the opening a portion inclined in the radial direction providing the outward tapper is provided for conveniently pouring beverage out of the beverage container. Below the outward tapper the concave portion is provided that extends radially from the inner of the beverage container to the outer of the beverage container.

As soon as the locking arms are pushed downward in the direction of the concave portion, the locking arms extend radially and engage in the concave portion, such that the locking mechanism locks the closure element to the beverage container that closure element cannot be moved downward or upward.

In one embodiment the locking mechanism can only be moved outward (upward), if the mechanical resistance caused by the locking arms engaging into the concave portion is surmounted. The mechanical resistance is caused by the locking arms that are pushed radially inward to the elastic portion of the locking arms. As soon as the locking arms have been pressed inwardly by the boarder or edge of the concave portion, the locking mechanism and closure element can be moved upwardly and the locking arms are released as soon as they are in contact with the inclined portion of the upper tapper at the opening.

The locking arms engage into the concave portion extending radially outward in the container in a snap/fit manner. Operation of such snap/fit mechanism is known by the person skilling the art.

In one embodiment the beverage container may comprise a plurality of concave portions, such as one concave portion for each locking arm.

Within the recess an elastic element 691, 692, such as a spring may be located pressing the contact element 622, 626 in the radial outward direction.

Particularly, when the closure element 606 is positioned in the beverage container as is shown in FIG. 3, the contact elements 622, 626 are guided by a recess in the locking arms 612, 616 and biased by the elastic elements in the radially outward direction, such that the radially outward portion of the contact elements 622, 626 engages in the concave portion 664 of the beverage container 602. Thereby, the closure element 606 is held firmly by the concave portion 664 and the contact element.

At the radially outer portion of the contact elements 622, 624, 626, 628 a sphere 623, 625, 627 is arranged. The sphere 623, 625, 627 may be rotatably accommodated within the contact element 612, 614, 616, 618.

FIG. 3 shows the closure element 606 and the locking mechanism formed by the locking arms 612, 614, 616, 618 in its locked position. The closure element 606 further comprises an actuation element 609 forming also a grip element. A user can touch the actuation element 609 in order to move the closure element 606 into the opening 601 of the beverage container or to remove the closure element 606 from the opening 601 of the beverage container 606.

For removing the closure element 606 from the opening 601 of the beverage container 602, the user has to shift the actuation element 609 vertically upward. At the actuation element 609 first profile elements 609 a are arranged. The first profile elements 609 a engage with second profile elements 609 b that are connected with the elastic elements and biasing the contact elements 622 and 626 into the locked position shown in FIG. 3. As soon as the user moves the actuation element 609 in the vertically upward direction, the first profile element 609 a and the second profile element 609 b disengage. Consequently, the second profile element 609 b is moved in the radially inward direction and consequently the elastic elements are moved radially inward. Hence, also the contact elements 622 and 626 including the spheres 623 and 627 are moved radially inward. Therefore, contact elements 622, 626 including the spheres 623, 627 disengage from the concave portion 664 and the user can remove the closure element 606 from the opening 601 of the beverage container 602.

The closure element 606 comprises a lid 610 closing the opening 601, when the closure element 606 is engaged with the concave portion 664 by the contact elements 622, 626. The lid 610 is held by rods 634, 636 and 638 extending from the lower surface of the lid. The rods 634, 636, 638 extend essentially in vertical direction from the lower surface of the lid 610.

The rods 634, 636, 638 extend through openings 635, 637, 639 in the locking arms 612, 614, 616, 618. In the embodiments shown in FIGS. 1 to 6 the openings 635, 637, 639 are formed as elongated holes or in an elliptical shape. On the first side of the rods 634, 636, 638 the lid 610 is arranged. On the second side of the rods 634, 636, 638 opposite to the first side an optional counter weight 632 is arranged. The counterweight 632 may act as a stop means 632 that is mounted to at least one of the rods 634, 636, 638 at a position opposite to the lid and restricts the pivoting angle range of the lid 610.

When the user rotates the smart carafe 600 around the horizontal axis, the lid 610 is held in a horizontal position, since the rods 634, 636, 638 are moveably arranged in the opening 635, 637, 639. The counter weight 632 additionally supports the horizontal position of the lid 610 independent of the angle of the smart carafe 600 relative to the horizontal axis.

With reference to FIGS. 1 and 3 a further aspect of the smart carafe 600 according to the present invention is explained. The controller 604 can output a signal to a light emitter 670. Consequently, the light emitter 670 outputs light rays 672 passing through beverage in the beverage container 602. The light rays 672 pass a hollow portion 674 in the actuation element 609. The light rays 672 impinge on a light distribution element 608 that may also act as a grip portion. The light emitter element 608 scatters the light rays 672 such that the impinging light rays are directed to the periphery of the smart carafe 600 and visible for a user. The light distributor element may have opaque optical properties, scattering optical properties and/or diffracting optical properties for distributing the light around the smart carafe 600.

The light emitter 670 may be the light emitting diode (LED), a laser diode or the like. The light emitter may transmit light in a single color or may emit light in a plurality of different colors e. g. by a plurality of light emitters. The light emitter may transmit continuous light, flashing light or light periodically changing color for transmitting information.

The controller 604 may comprise a rechargeable battery 680, a processor 682, a fill level sensor 684 and a first temperature sensor 686. The fill level sensor 684 can be a weight sensor determining the weight of the beverage container 602 and the beverage therein. The first temperature sensor 686 can determine the temperature of the beverage in the beverage vessel 602. The processor 682 is coupled with the fill level sensor 684, the first temperature sensor 686 and the light emitter 670.
